[Congenital megacolon presented as fecaloma and urinary tract infection. Report of one case].

A 5-month old boy was admitted with urinary tract infection. While doing the voiding cystogram, the bladder was found to be pushed to the right side by a soft tissue mass. Through CT scan examination, the mass revealed to be a fecaloma. Through rectal suction biopsy and barium enema study for megacolon, it was proved to be a case of congenital megacolon. A pull-through operation for megacolon was carried out. He recovered quickly, and was discharged 10 days later. We make this report in order to discuss this rare presentation which may occur in congenital megacolon.
